After a meeting of the Michigan Science Fantasy Society in November of 1949, two members set off a bomb in the front yard of Rapp's home. Police were called and neighbours gathered, and according to Rapp in an open letter he wrote of the incident, the bomb was heard from two miles away. Immediately after, Rapp quit MSFS but didn't end his zine till the next year, when he left the U.S. for military duty in Korea. He then turned the zine over to F. Towner Laney and Charles Burbee to edit. They put out two issues, the last, in 1950, called the "Insurgent Issue".
